Scientists have discovered a quasicrystal, a bizarre form of matter that defies the normal rules of symmetry in crystals, in the debris of the first nuclear detonation in history. Forged on July 16, 1945 during the Trinity nuclear bomb test in New Mexico, the quasicrystal is the oldest known structure of its kind made by humans.

The amazing find was achieved by a team co-led by Luca Bindi, chair of mineralogy and crystallography and head of the department of Earth sciences of the University of Florence. Bindi and his colleagues emphasized that the newly identified quasicrystal is the “the first to be identified in the remnants of an atomic blast” and contains “a hitherto unknown composition,” according to a study published on Monday in the Proceedings of the National Academy of Sciences.
